I just received my HIS Radeon x800XL in the mail today. I knew I was going to have some issues installing the card as I had replaced the stock heatsink on my ASUS A8N-SLI with a larger ThermalRight NB-1 heatsink. I removed all the cards from my system and pull out the motherboard. I took the heatsink out and made some quick checks to see just how bad the modification was going to be..
